description="
The Free OpenGL Utility Toolkit.

FreeGLUT is a free-software/open-source alternative to the OpenGL
Utility Toolkit (GLUT) library.  GLUT was originally written by
Mark Kilgard to support the sample programs in the second edition
OpenGL 'RedBook'.  Since then, GLUT has been used in a wide variety of
practical applications because it is simple, widely available and
highly portable.
